There's no need for hearsay on this. This is a true statement.
During the construction of New York's East Side Access subway project, union rules required 18 workers to run and supervise one of the tunneling machines. The manufacturers of the machine say no more than six are required to do this, which is how many are used in hardly-slave-labor countries like Norway.
Underground construction projects usually require three to four times as many staff in NYC as they do in Asia or Europe.
